This very scarce chart of San Francisco Bay was made during a voyage to the Pacific from 1836-39 by Captain Abel Aubert Dupetit Thouars in command of the Venus. The bay is well delineated with soundings and profile views. France was interested in obtaining territory from the Mexican government in exchange for the millions of dollars worth of loans that the French government had given to Mexico, and which the Mexican government had defaulted on. They sent Captain Dupetit Thouars to survey the region and see what it offered, as well as to inject a French presence to bolster any claims they had in the Pacific. The chart was engraved by Jacobs, and drawn by J. M. Hacq. Notation of Prix Un Franc lower right.
